Problems solved by technology

This kind of oil circuit design is relatively complicated, the lubricating oil transmission route is long, and the response time is increased, resulting in a large pressure loss during the lubricating oil transmission process, so the lubricating oil transmission efficiency is relatively low
[0006] In addition, since the overhead camshaft of the engine also has an engine braking system, more lubricating oil volume and higher and more stable lubricating oil pressure are required, and the traditional oil circuit design cannot meet its demand for lubricating oil

Abstract

The invention provides a lubricating system of an engine. The lubricating system of the engine comprises a main oil way arranged on an engine cylinder body and an auxiliary oil way communicated with the main oil way. The auxiliary oil way comprises a cylinder cover with an opening facing the engine, a vertical oil way used for lubricating the cylinder cover and a transverse oil way communicated between the main oil way and the vertical oil way, and the transverse oil way is arranged between two adjacent cylinders of the engine. According to the lubricating system of the engine, the vertical oil way and the transverse oil way are arranged in the middle of the engine, a conveying line of lubricating oil is shortened, pressure loss in the conveying process of the lubricating oil is reduced, and therefore the conveying efficiency of the lubricating oil is improved. Meanwhile, the requirements for the lubricating oil of an overhead camshaft of the engine are met. In addition, the requirement for lubricating of a crank shaft, a connection rod and an auxiliary part on the lateral face of the cylinder body is simultaneously met, the design requirements for other auxiliary oil ways are reduced, the conveying line of the lubricating oil is simplified, the manufacturing process is relatively simple, and the machining cost is reduced. The invention further provides the engine.

Description

technical field [0001] The present invention relates to the technical field of engine lubricating systems, more specifically, relates to an engine lubricating system, and the present invention also relates to an engine having the above-mentioned engine lubricating system. Background technique [0002] The engine is usually composed of two major mechanisms and five systems, namely the crank connecting rod mechanism, the valve mechanism, the fuel supply system, the ignition system, the cooling system, the lubrication system and the starting system. Among them, the lubrication system is composed of oil pan, filter, oil pump, oil cooler, oil filter, main oil passage, multiple auxiliary oil passages and other structures. [0003] Since the cylinder body of the engine is under very complicated stress conditions when it is working, especially for high-power engines, the working condition is very bad. In order to ensure that various systems can work reliably and coordinately, it is ...
